Hmm, there aren't a lot of things you can do with them, no?

As long as it works I don't see a problem.  I have said before that we
should allow using the iconv interface because it's more powerful.

No.  This could be tricky to do though without sacrificing the designed
efficiency of the "name" type.  For instance, how could we store the
which-locale-is-it information?
